Vlad Tenev ought to be penning a very nicely worded thank-you card to SEC Chair Gary Gensler. The commission is throwing Tenev and his fellow Robinhoodies a much needed lifeline with its decision to not ban payment for order flow, the contentious practice brokerages like Robinhood rely on to make money, according to a Bloomberg report.

The company’s trading revenue was down 55% in the June quarter, compared to one year prior.
